Let's divide 403638 by 57
Let's see how many times 57 fits into 403638.

Step 1:
4 divided by 57 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 57

On to step 2:
The number 57 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 57

Step 3:
If we divide 403 by 57, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 399 away from 403, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 57

Step 4:
If we divide 46 by 57, we get 0 and a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Subtract 0 from 46 to get 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 57

On to step 5:
If we divide 463 by 57, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 708.0
Deduct 456 from 463 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 57

Going ahead to step 6:
When dividing 78 by 57, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 7081.0
If we subtract 57 from 78, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
210 divided by 57 is 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 7081.3
Subtracting 171 from 210 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
When dividing 390 by 57, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 7081.36
Subtract 342 from 390 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
57 can be fit into 480 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 7081.368
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
The number 57 fits into 240 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 7081.3684
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 57 fits into 120 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 7081.36842
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
57 can be fit into 60 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 7081.368421
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
If we divide 30 by 57, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 7081.368421
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
57 can be fit into 300 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7081.36842105
Subtract 285 from 300 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 7081.36842105 and a remainder of 1.5e-08.
